Abstract

The locking bar (48) arrests itself in release setting and is moved into the fix setting by outside power. The specifically hydraulic motor (90) cuts out in the release setting. The tool is slewed by hydraulic cylinder relative the hoist and the bar during this contacts the hoist and in so doing moves into its fix setting. The motor is remotely controlled by an operators stand valve, and has its own pressure accumulator which couples to an hydraulic cylinder space loaded here to guide the bar into the fix setting as required. In this condition the motor (90) connects to a now-depressurized cylinder chamber. The bar moves along a slotway made up of small and larger width sectors and endstop (76) arrests the bar in the release setting by abutting the narrower sector of the slotway.
